it is not just that people have specific disagreements with him on iran or on israel. but i think many republicans see him as a man who sort of strayed from the flock. sometimes you take the criticism most strongly from your own people if they feel like you haven't been true to the cause so to speak. senator hagel his defenders and his fans and i think i'm one of them would say he displayed admirable thought. kit there has been some issues i will take the iraq surge for example where he was against it at the beginning. a lot of us were dubious about it at the beginning but one isn't quite sure if he revised his views once it clearly succeeded in its own military logic. itle be interesting to see what he will say in the confirmation hearings. that will reflect to which he is empirical and open minded and open to new evidence. those are some of the questions he will have to confront. >> shepard: some are making the argument this is a man who will bring into the public discourse the failures in iraq and afghanistan as they might relate to anything going forward with iran.
